I have been searching for a good spec of an Achilles tang for 2 years and have finally found one. He is about 5" and has no HLLE, or ich, or no sunken belly. I put him on hold for a day and during that time I watched him eat live brine and nori, amazing... I have had him home for 3 days now and he is eating Omega Marine flakes and Kelp flakes. The tank he is currently in is a 40g breeder with little to no stress (royal dotty, 2 maroon clowns, blenny, and fairy wrasse)....I know, I know...not big enough....I have to rearrange the 125 in the basement before I put him in. 3 days and he is starting to show signs of ich....what should I do?...usually I wait it out....ya I know you should have quarantined him....does anyone else out there have an Achilles?
